FIELD OF THE INVENTION

This invention relates to a system and method for securely storing, retrieving and sharing data using PCs and mobile devices and for controlling and tracking the movement of data to and from a variety of computing and storage devices.

BACKGROUND OF THE INVENTION

The number of personal computers and mobile devices capable of sending and storing data increases significantly each year. These devices are routinely used to store files containing personal as well as confidential business information. Security administrators and business owners often have no record of what data is stored on PCs and mobile devices at any given point in time. For example, if a computing or storage device is lost or stolen, it is problematic to determine after the fact exactly what information was lost and/or disclosed with the device. There are also significant regulatory exposures related to the disclosure of certain classes of data such as medical information (HIPAA) and Payment Card Industry (PCI) data.

Individuals and businesses often share data files by sending these files as email attachments over the Internet. Although encryption methods are available, many users do not encrypt attachments prior to email transmission. Therefore, there is a risk that data files sent as attachments in email messages may be disclosed to an unauthorized recipient. Furthermore, using current methods, security administrators and business owners have no reliable mechanisms to control or track the movement of data sent by email between users of PCs or mobile devices.

In recent years the numbers of mobile storage devices such as USB flash drives and mobile communication devices with internal, non-volatile flash memory have also increased significantly. A significant amount of personal and confidential data can be stored on USB flash drives and mobile communication devices with non-volatile storage such as micro SD cards. Conventional methods allow data to be encrypted prior to storage onto these devices; however, conventional methods lack a mechanism for limiting access to confidential data once stored on these devices. Furthermore, there are no current methods which can serve to monitor and control the movement of data from non-volatile flash memory to other computing devices. Because laptop computers are highly mobile, it is not uncommon for laptop computers to fall outside of the regular backup processes which otherwise may be in place for fixed (desktop) PCs and corporate servers. Recognizing this need, there has been a trend in new services (such as Carbonite, Iron Mountain, RackSpace/Jungle Disk, and EMC/Mozy) that offer remote backup services to backup the data stored on laptop PCs. However, these services lack capabilities for security administrators and business owners to track, monitor and enforce compliance with policies. Also, using these products, there is little utility value that can be derived from the remotely stored data for purposes beyond simple backup and restore. Specifically, these remote backup services do not offer users the ability to ubiquitously access and/or share backed-up data from thin-client (WEB) or mobile (WAP) based interfaces.

Along with the trend in mobile computing, there has been an increased demand for Internet access and data sharing from a variety of users and businesses. Today, wireless broadband modems enable the mobile user to gain internet access using the cellular networks of wireless network operators such as (AT&T, Verizon, T-Mobile, and Sprint). However, these carriers have limited capacity to support peer-to-peer data transfers over wireless networks. Many of these same wireless carriers also offer DSL-based or Cable-based high speed Internet access. These high speed data services have become highly commoditized in recent years with the key competitive focus on download speeds. Within the major carriers (AT&T, Verizon, Sprint), there is little functional or technical synergy between wireless and wired services. Carriers need new value-added services that can increase customer retention and bridge the gaps between wired and wireless-based services. Services such as secure remote file storage and secure file sharing would be effective value added offerings for the adept mobile network operator interested in proactively managing its limited wireless network resources and looking for new sources of revenue and increasing customer retention.

Given these collective limitations of the prior art and the numerous needs and opportunities stated herein, a system and method are needed that can provide an architecture for securely storing, retrieving, and sharing data using PCs and mobile devices and for controlling and tracking the movement of data to and from a variety of devices.

SUMMARY OF THE INVENTION

The invention satisfies the above-described and other related needs by providing a method and system for security administrators, business owners and individuals to know what data is stored on mobile devices; to limit how data is shared between users; to track the movement of data between users, PCs, and mobile devices; and to provide ubiquitous access to remote data based on a multi-factor security framework.

In one exemplary embodiment, the invention provides a method for mobile data security. A mobile device can include a stored computer software program and database. The mobile device can be connected to a first PC operable to validate the device based on security settings that can be accessed from a remote computing device. Upon validation, data can be transferred from the first PC onto the mobile device. The first PC can communicate to the remote computing device the details related to the files that were transferred to the mobile device. These details related to the files that were transferred from the first PC to the mobile device can be stored on the remote computing device as meta-data logs. The mobile device can later be connected to a second PC operable to receive files transferred from the mobile device. The second PC can communicate to the remote computing device the details related to the files that were received from the mobile device. These details related to the files that were transferred from the mobile device to the second PC can be stored on the remote computing device as meta-data logs.

In another exemplary embodiment, the invention provides a system for mobile data security. A mobile device can include a stored computer software program and database. The mobile device can be connected to a first PC operable to validate the device based on security settings that can be accessed from a remote computing device. Upon validation, data can be transferred from the first PC onto the mobile device. The first PC can communicate to the remote computing device the details related to the files that were transferred to the mobile device. These details related to the files that were transferred from the first PC to the mobile device can be stored on the remote computing device as meta-data logs. The mobile device can later be connected to a second PC operable to receive files transferred from the mobile device.

These details related to the files that were transferred from the mobile device to the second PC can be stored on the remote computing device as meta-data logs.

In yet another exemplary embodiment, the invention comprises a method for multi-factor remote data access. A multi-factor authentication system uses three or more unique pieces of information to verify the identity of a person or other entity requesting access under security constraints. A mobile device can be connected to a first PC. The mobile device can include a stored computer software program and database. The first PC can be operable to execute the software stored on the mobile device. The software on the mobile device can transfer data from the first PC to a remote storage device comprised within a remote computing device. A record of the details related to the data that is transferred from the first PC to the remote storage device can be stored in the database on the mobile device. A corresponding record of the details of the data that is transferred from the first PC to the remote storage device can be stored on the remote computing device as meta-data logs. The mobile storage device can be connected to a second PC. The second PC can be operable to execute the software stored on the mobile device. Using security settings that can be stored on the remote computing device, the software on the mobile device can validate if the second PC is authorized to receive data that was previously transferred from the first PC. If the second PC is authorized to receive data from the first PC, the software on the mobile device can transfer data from the remote storage device to the second PC. A record of the details of the data that can be transferred from the remote storage device to the second PC can be stored as meta-data on the remote computing device. A corresponding record of the details of the data that can be transferred from the remote storage device to the second PC can be stored in the database on the mobile device.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The present invention answers these needs by providing several approaches for systems and methods for securely storing, sharing, and tracking the movement of data on PCs and mobile devices.

In embodiments of the present invention as illustrated in FIG. 1, a mobile storage device (1.2) comprising a non-volatile flash memory, software application and database is physically connected to PC (1.1). Upon connection with the mobile device, the CPU of PC (1.1) executes software application (1.2.2) and identifies the mobile device (1.2) using data contained in message (1.2.1). PC (1.1) sends authentication request (1.1.1) to remote computing device (1.5). The authentication request (1.1.1) contains a unique mobile device serial number and a unique software license key that are passed from the mobile device (1.2) to the PC (1.1) using message (1.2.1). The authentication request (1.1.1) also contains a serial number to uniquely identify the PC (1.1). The remote computing device (1.5) receives the authentication request (1.1.1) from PC (1.1). The remote computing device (1.5) retrieves from the security settings file (1.6) unique security settings related to the mobile device using the unique software license key and validates that the license key is authorized for use with the mobile device.

If the license key and mobile device serial numbers are determined to be a valid combination, the software application is further validated to determine if it is authorized for use on the connected PC (1.1). If the mobile device (1.2) and software license key for software application (1.2.2) are valid for use with PC (1.1), message (1.6.1) is returned to PC (1.1) indicating that data may be transferred from PC (1.1) onto mobile device (1.2) using message (1.1.2).

Upon receipt of message (1.1.2) the software application (1.2.2) copies transferred data into the database (1.2.4). Data is encrypted prior to storage into database (1.2.4) using an encryption key that is uniquely related to the license key for software application (1.2.2). Software application (1.2.2) executed using the CPU and network resources of PC (1.1) stores details (which can include one or more of: file names, date created, date stored, originating PC, and originating volume) related to data transferred to the mobile storage device into mobile device database (1.2.4) and sends message (1.1.3) to remote computing device (1.5) containing same details of data transferred from PC (1.1) to mobile device (1.2). Message (1.1.3) is received by remote computing device (1.5) and stored as meta-data logs (1.3).

Mobile device (1.2) is then disconnected from PC (1.1) and connected to PC (1.4). Upon connection with the mobile device, PC (1.4) executes software application (1.2.2) and identifies the mobile device (1.2) with data contained in message (1.2.3). The authentication request (1.4.1) contains a unique mobile device serial number and a unique software license key that are first passed from the mobile device (1.2) to the PC (1.4) using message (1.2.3).

The remote computing device (1.5) receives the authentication request (1.4.1) from PC (1.4). The remote computing device (1.5) retrieves from the security settings file (1.6) the unique settings related to the mobile device using the unique software license key and validates that the license key is authorized for use with the mobile device. If the license key and mobile device serial numbers are determined to be a valid combination, the software application is further validated to determine if it is authorized for use on the connected PC (1.4). If the mobile device (1.2) and software license key for software application (1.2.2) are valid for use with PC (1.4), message (1.6.2) is returned to software application (1.2.2) executed by PC (1.4) indicating that data may be transferred from mobile device (1.2) to PC (1.4).

Data is then transferred from mobile device (1.2) onto PC (1.4) using message (1.2.5). Data is decrypted prior to storage using an encryption key that is uniquely related to the license key for software application (1.2.2). Software application (1.2.2) executed using the CPU and network resources of PC (1.4) stores details (e.g. file names, date transferred, destination PC, destination volume) related to each file transferred from the mobile storage device to the PC (1.4) into mobile device database (1.2.4) and sends message (1.4.2) containing the same details of data transferred from mobile device (1.2) to PC (1.4). Message (1.4.2) is received by remote computing device (1.5) and stored as meta-data logs (1.3). It should be appreciated by those who are skilled in the art that a variety of methods of communication between the PCs, mobile devices, and the remote computing device (e.g. http, https, xml, ftp, etc.) may be used and the invention should not be construed as limited to any one set communication protocol or data format.

In other embodiments of the present invention as illustrated in FIG. 2, a mobile communication device (2.2) comprising at least a CPU, operating system, wireless antenna, non-volatile flash memory, software application and database is connected to PC (2.1) using a wireless communication method such as Bluetooth or other near field communication (NFC) method.

PC (2.1) sends authentication request (2.1.1) to remote computing device (2.5). The authentication request (2.1.1) contains a unique mobile device serial number and a unique software license key that are passed from the mobile device (2.2) to the PC (2.1) using message (2.2.1). The authentication request (2.1.1) also contains a serial number to uniquely identify the PC (2.1). The remote computing device (2.5) receives the authentication request (2.1.1) from PC (2.1). The remote computing device (2.5) retrieves from the security settings file (2.6) unique security settings related to the mobile device using the unique software license key and validates that the license key is authorized for use with the mobile device. If the license key and mobile device serial numbers are determined to be a valid combination, the software application is further validated to determine if it is authorized for use on the connected PC (2.1).

If the mobile device (2.2) and software license key for software application (2.2.2) are valid for use with PC (2.1), message (2.6.1) is returned to PC (2.1) indicating that data may be transferred from PC (2.1) onto mobile device (2.2) using message (2.1.2). Upon receipt of message (2.1.2), the software application (2.2.2) copies transferred data into the database (2.2.4). Data is encrypted prior to storage into database (2.2.4) using an encryption key that is uniquely related to the license key for software application (2.2.2). Software application (2.2.2) executed using the CPU and network resources of PC (2.1) stores details (which can include one or more of: file name, date created, date stored, originating PC, and originating volume) related to data transferred to the mobile storage device into mobile device database (2.2.4) and sends message (2.1.3) to remote computing device (2.5) containing details of data transferred from PC (2.1) to mobile device (2.2).
